Other members, however, including Tunkin and Waldock himself, pointed out, with some reason, that the two situations were different: where ratification was concerned, “a State could obtain all the time it required by the simple process of delaying ratification until it had made the necessary adjustments to its municipal law”; in the case of the withdrawal of a reservation, by contrast, “the change in the situation did not depend on the will of the other State concerned, but on the will of the reserving State which decided” to withdraw it.
Sin embargo, otros miembros, en particular Tounkine y el propio Waldock, destacaron, no sin razón, que las dos situaciones eran diferentes: en lo tocante a la ratificación "el Estado puede disponer de todo el tiempo que necesite con sólo abstenerse de rectificarlo en tanto no haya efectuado los reajustes necesarios en su derecho interno"; por el contrario, en el caso del retiro de una reserva, "el cambio en la situación es ajeno a la voluntad del Estado interesado, pues depende de la decisión del Estado autor de la reserva de retirar ésta".
